Electronic waste or e-waste pose a serious challenge in their disposal. The printed circuit boards (PCBs) present in discarded electronic devices like smartphones and computers contain toxic chemicals and metals that can get into the soil or water if thrown in landfills or burnt. Now, scientists have designed a novel technique to dispose them by simply powdering them using a cryomill. This, they claim, can completely recover the polymers and metals for recycling in an eco-friendly way, ensuring zero waste.
